An AFR gage isn't going to help.
AFR numbers aren't targets. They're reference points. Performance is how to determine if each change is toward or away from the goal.
Save your money and spend the time learning what each circuit does. Then you'll understand why the sequence in tuning is important and you'll not head off on the wild goose chase. Each of these changeable components has a purpose which can be tied to a specific result.
Learning to use an AFR gage is another learning curve. Going that far and a logger with rpm, and preferable also at least MAP or TPS will be more enlightning - but yes more learning.
You can save money and time by learning what the circuits do, and starting at the begining, tune one circuit at a time judging each change based on whether it improves power or efficiency.
